Application filed zui e,

My adapted to retain against the umbris folded and RIB LOCK roe UMBRELLAs.

ck for unibrellas 1n snug relation hen the umbrella.

to allow-rolling of the lock on to the handle to allow opening of the umbrella. a

My invention in particular comprises a type of resilient ring or which may around the elastic bracelet be inserted over the end or handle of the umbrella and fastened in place with a suitable catch, bayonet or screw threaded joint.

The rib lock is made of a tight helically coiled spring which may be passed around the handle or the ribs of the umbrella at the up and by means or a clasp e per ends thereof t a suitable type hold the wire grip lock in position.

hjiy invent on will be more readily understood iironi the following drawings, in which description and Figure 1 is a perspective view of an umbrella showing my rib lock in position engaging the upper ends of the ribs and holding them in snug position against the rod.

showing the type of coil spring used and the bayonet type fittings for each end.

Fig. 4c is a perspective view of the plug end of a bayonet fitting.

Fig. 5 is a view of the socket end of the bayonet fitting.

Fig. 6 1S a view of the rib lock bent into a circle with the bayonet end clasped holding the device in a circle. Fig. 7 is another type a screw threaded connect two ends and the spring.

Fig.

of joint showing ion between the 8 is a sectional view of still another type of joint showing prongs to engage in a flanged socket.

Fig. 9 is another type of rib lock inwhich the helical spring is soldered or welded at the ends forming a continuous helix bent into a circle.

in the drawings, the umbrella is designated generally by the numeral 1, having a handle 2, a rod 3, ribs t and a cover 5.

The rib lock is designated numeral 6 and is shown in around the upper ends of generally by the Fig. 1 tightened the ribs and in 1. .25. Serial No. 42,465.

Fig92 as being rolled upwardly on the lower end of the handle. I Referring to Figs. 3 to 6, the lockis formed by a tightly coiled wire 7 coiled into the form of a helix. I a bayonet plug 8 having a barrel section 9, a reduced stem 10 and a prong 11 projecting from one side of the stem adjacent its outer end. The plug is secured to the open end of the spring by inserting the barrel section 9 within the spring and preferably soldering or welding the spring and barrel togetherbayonet joint 13 is formed of a ring 14 of suificientexternal diameter to fit snugly in the plug 8 and to be secured therein preferably by soldering or welding. The ring has an" internal circular section 15 of substantially the same diameter as the stem 10 of the plug and has a slot 16 insertion of the prong 11. After inserting the prong through the slot it is given a turn and seats in a recess 17 formed in the under face of the ring 14.

The plug and socket are preferably secured to the ends of the spring so that the spring will require to be slightly twisted as if winding tighter to insert the prong through the slot and in tending to unwind the spring draws the prong into the recess 17 The tension of the spring then draws the prong into tight engagement with the recess and prevents them becoming accidentally unlatched. When so connected the rib lock has the appearance shown in Fig. 6.

In the construction of Fig. 7 an internally screw threaded socket 20 having a cylindrical outside surface 21 is secured in one end of the spring 7 in a manner above described.

end of the spring opposite the therethrough for the At one end is The socket end 12 of the tighter several or more turns than its usual normal position and the screw threaded stem 25 is inserted in the screw threaded socket 20 so that the tendency of the spring to unwind screws the vt'wo ends together and holds them thus tightly locked.

shaped ends 35 are inserted in the socket so that the hooks engage the inner surface of the flange 31 and thus holds the two ends of the spring in tight engagement.

In Fig. 9 the two ends of the spring 7 are indicated by the numeral 36 as being secured together by soldering, welding or the like, thus forming an elastic ring of the size desired.

It is intended that the elastic wire ring when placed on the handle of an umbrella will be left thereon, hence the dillerent types or clasps may be made to have a tight fit. My invention may be made up of any suitable materials, being made of expensive material to harmonize with costly umbrellas or to be made of relatively cheap spring steel wire if desired. My invention may also be modified to suit particular adaptations of the ring elastic spring without departing from the spirit of my invention.

' Having described my invention, what I claim is V In a resilient ring having a wire twisted to -form a helix, such wire being formed of spring metal, a socket member formed of an annular ring having a slot on the inner periphery or" the ring and a recess on the inner surface, the said ring being attached to one end of the wire coil, a plug attached to the other end of the wire coil, such plug having a barrel section 01" substantially the interior diameter of the coil and a reduced stein extending outwardly therefrom, the stem having a prong adapted to pass through the slot in the ring and to engage in the recess in the underside of the ring, to hold the wire in a ci 'cular position,

in testimony whereof I have signed my name to this specification.
